Hbase and Ranger - Hbase Police test connection failed | Unable to check availability of Hbase environment

Hbase and Ranger - Hbase Police test connection failed | Unable to check availability of Hbase environment

New Contributor

Hi everyone, we have a strange issue with an actual HDP setup for our dev environment. We installed - like many times before - ranger and enabled the ranger plugins. We created the polices for our services in Ranger and Hive works, HDFS works, Knox works, Yarn works fine.. but testing the connection to hbase doesn't work and we have no idea why. That's our first installation with HDP 2.6, but we installed and using many clusters of the previous versions (2.0 - 2.5).

The failure:

Testing connection for habse in ranger - the popup error:

org.apache.ranger.plugin.client.HadoopException: getHBaseStatus: 
Unable to check availability of Hbase environment 
[multinode-hdpqa_hbase].. 
getHBaseStatus: Unable to check availability of Hbase environment [multinode-hdpqa_hbase].. 
java.lang.reflect.InvocationTargetException. 
Could not initialize class org.apache.hadoop.hbase.protobuf.ProtobufUtil.

There are no errors in the hdfs, hbase, zookeeper, phoenix or yarn logs...

The facts:

The credentials are correct, hbase works fine - also with the users and the audit in ranger,

HDP-Version: HDP-2.6.0.3

Cluster: 6 Nodes - each node with 64 GB RAM, 8 Cores and a bunch of storage

Environment: DEV (testing cluster)

Services installed:

HDFS, YARN, MapReduce2, Tez, Hive, HBase, Pig, Sqoop, ZooKeeper, Ambari Infra, Ambari Metrics, Kafka, Knox, Ranger, Spark2, Zeppelin Notebook, Slider

Security:

Simple (SSL, Knox with LDAP Demo, Unix...)

Any ideas?

Best regards,

Jan

@Jan Lenhardt

is this a HA cluster? If so could you please link core-site.xml and hdfs-site.xml to the the ranger/conf folder, restart ranger and try?

Hi, we are also facing similar issue , just wanted to make sure when we say link to ranger/conf means create a soft link for hdfs-site.xml/core-site.xml point ranger/conf folder or am I missing something , sorry I am new to hadoop.

Hi Ramesh, yes it is a HA-Cluster.

You're right! Thank you for your answer. The link to the hdfs-site.xml was broken. I fixed it and everything works fine. ;) Best,

Jan
